I5-2500k @ Stock Speeds Idling High with Aftermarket Cooler

[crux315]

Hi there,

I'm running an i5-2500k on my aftermarket cooler, this one (http://www.newegg.com/Product/Product.aspx?Item=N82E16835185142) and I'm using this fan on it (http://www.newegg.com/Product/Product.aspx?Item=N82E16835608004) instead of the stock one that it came with. Now, I'm just wondering why is it idling at 37c-41c at room temperature inside my HAF 922 with the case side closed? I'm really confused because when it starts up, it's idling at ~32c, but then overtime, it just gradually gets up to the point of where it stays at that temperature. Oh, and if this is anything, it's only at about ~46c-54c while I'm running Battlefield 3.

Checking Task Manager, my CPU usage is really around 10-12% while I'm writing this.

its because automatic fan speeds keep the fans low to lower noise and power use unless you need it. Why does idle temperature matter that much?

~5-10C above roomtemp at idle is normal. Your gaming temps are fine so I'm going to assume load temps are good and that is really all that matters.
